ViewPoint™ Centrifuge Tubes

ViewPoint™ tubes transition from clear to blue when exposed to cold temperatures. This multi-step and reversible thermochromic transition offers real-time temperature signaling to indicate fluctuations above and below 4 °C. Above 4 °C, ViewPoint™ tubes are clear and transparent. At 4 °C, ViewPoint™ tubes transition to light blue and become slightly opaque. At 0 °C, ViewPoint™ tubes reach their full progressive transition to dark blue, are completely opaque, and provide protection from Ultraviolet (UV) light.

Real-time temperature signaling alerts the researcher to potentially harmful ice crystal formation and enables the maintenance of the desired temperature throughout experimentation.

ViewPoint™ thermochromic centrifuge tubes are made from an ultra-clear medical grade resin and engineered with thick, durable walls for higher speed centrifugation. They consistently outperform other brands and are designed to withstand breakage and leakage during centrifugation, autoclaving (121°C), or when frozen (-80°C).
Labcon’s SuperSeal™ leak-resistant flat caps keep your tubes completely secure and the transparent, extra-large writing panel is smudge resistant and easy to see through.

Specification:

• Caps include integral moulded elastomeric seal for a leakproof seal
• Spin to 12.500 xG for 15mL and 50mL; 40,000 xG for the 1.5mL tubes
• Freezable 121°C to -80°C and autoclavable
• When dark blue (0 °C), ViewPoint™ tubes provide protection from Ultraviolet (UV) light

Quality:

• All ViewPoint™ Centrifuge Tubes are made of high quality 100% pure virgin medical grade polypropylene. Resins are pre-tested to ensure no extractables are present (free of DiHEMDA, oleamide, and BPA).
• Every lot of centrifuge tubes is lab tested and certified free of detectable ATP, Nuclease (RNase/DNase), Endotoxin (pyrogen) contamination and certified to U.S.P. results.
• Cytotoxicity testing includes: Endotoxin (Pyrogen) Free, Sperm Motility Assay (SMA), Mouse Embryo Assay (MEA). Compliant with FDA CFR Title 21-177.1520, 178.3295, 178.3297 and ISO 10993-3.
